Continuous humidity measurement in gas-insulated ...static.progressivemediagroup.com/Uploads/CaseStudy/...· PDF filedemand for control systems with online dew-point measurement has risen sharply in recent years. The new GDHT-20 from WIKA is capable of measuring the relative humidity, pressure and temperature precisely over a wide measuring range. This high-accuracy transmitter enables a continuous and digital monitoring of gas-insulated switchgear to be set up.
SF6 instrument transformers presentation base.ppt· PDF file10/18/2012· Non flammable gas insulation. Life time dielectric quality assured (no checks, no treatment). Total absence of partial discharges. Oil filling and periodical oil samplings are not required. Gas leakage < 0.1% a year. Remote control of the internal insulation level by means pressure gauge provided with an alarm threshold and lock threshold.
Eco-efficient ABB breaker technology ensures reliable ...'s LTA units use CO2 instead of the usual sulfur hexafluoride (SF6) gas as an insulating and arc extinguishing medium, because SF6 gas has much higher global warming potential than CO2.
Alstom Grid takes a leading position in the 820 KV DC ... While wall bushings are based on a pure gas and composite insulator technology, converter transformer bushings use a fully sealed oil impregnated paper (OIP) grading capacitor for the interface with the transformer and a composite insulator filled by SF6 gas for the part of the bushing that protrudes into the valve hall.
